==== DS9097 1-wire adapter pin-out (Latvian) ====
  * Red wire - +5V(100mA max) (not used in parasite setup)
  * //White wire - +3.3V(10mA max)// (not used in any setup)
  * Black wire- GND  (temp sensor edge pins)
  * Green wire- 1-wire data (temp sensor middle pins)

=== Testing ===
  * sudo apt-get install digitemp
  * sudo digitemp_DS9097 -s /dev/USB0 -w

==== Temp sensor pin-out ====
  * waterproof: 
    * white=data; black=gnd; red=V 
    * white -> solid color extension
    * red+black -> halfcolored extension
  * barebone:
    * middle leg = data -> solid color extension
    * edge legs -> halfcolored extension
